The Astros and Rockets each claim they are owed more than $27 million in unpaid rights fees by Comcast SportsNet Houston, according to documents filed yesterday in the network’s chapter 11 case, the Houston Chronicle reported today. The teams top a list of the 25 largest unsecured claims against the network, totaling about $60 million, submitted in advance of a hearing today before Bankruptcy Judge Marvin Isgur. The Astros, who own 46 percent of the partnership, and Rockets, who own 31 percent, are by far the largest unsecured creditors. The Astros, who were not paid their rights fees for the final three months of the 2013 season, are owed $27,898,563, and the Rockets, who have not been paid this season, are owed $27,683,693.
